CSS实现瀑布流布局

一、通过Multi-columns相关的属性column-count、column-gap配合break-inside来实现瀑布流布局

HTML

<div class="masonry">
    <div class="item" style="height: 50px;">1</div>
    <div class="item" style="height: 100px;">2</div>
    <div class="item" style="height: 150px;">3</div>
    <div class="item" style="height: 130px;">4</div>
    <div class="item" style="height: 210px;">5</div>
    <div class="item" style="height: 170px;">6</div>
    <div class="item" style="height: 60px;">7</div>
    <div class="item" style="height: 150px;">8</div>
    <div class="item" style="height: 80px;">9</div>
    <div class="item" style="height: 140px;">10</div>
    <div class="item" style="height: 100px;">11</div>
    <div class="item" style="height: 140px;">12</div>
    <div class="item" style="height: 130px;">13</div>
    <div class="item" style="height: 80px;">14</div>
    <div class="item" style="height: 120px;">15</div>
</div>

CSS

.masonry-column {
  column-count: 3;
  column-gap: 5px;

  .item {
    break-inside: avoid;
    box-sizing: border-box;
    border: 1px solid brown;
    margin-bottom: 7px;
    background-color: wheat;
    display: flex;
    align-items: center;
    justify-content: center;
    font-size: 50px;
    font-weight: bold;
    color: brown;
  }
}

　　

 二、通过FlexBox布局（需要强制设置height: 100vh;）

HTML

<div class="masonry-flex">
  <div class="item" style="height: 140px"></div>
  <div class="item" style="height: 190px"></div>
  <div class="item" style="height: 170px"></div>
  <div class="item" style="height: 120px"></div>
  <div class="item" style="height: 160px"></div>
  <div class="item" style="height: 180px"></div>
  <div class="item" style="height: 140px"></div>
  <div class="item" style="height: 150px"></div>
  <div class="item" style="height: 170px"></div>
  <div class="item" style="height: 170px"></div>
  <div class="item" style="height: 140px"></div>
  <div class="item" style="height: 190px"></div>
  <div class="item" style="height: 170px"></div>
  <div class="item" style="height: 120px"></div>
  <div class="item" style="height: 160px"></div>
  <div class="item" style="height: 180px"></div>
  <div class="item" style="height: 140px"></div>
  <div class="item" style="height: 150px"></div>
  <div class="item" style="height: 170px"></div>
  <div class="item" style="height: 170px"></div>
  <span class="item break"></span>
  <span class="item break"></span>
  <span class="item break"></span>
</div>

CSS

.masonry-flex {
  display: flex;
  flex-flow: column wrap;
  align-content: space-between;
  /* 容器必须有固定高度
   * 且高度大于最高的列高 */
  height: 1920px;
  /* 非必须 */
  background-color: #f7f7f7;
  border-radius: 3px;
  padding: 20px;
   100%;
  margin: 0 auto;
  counter-reset: items;
}

.item {
   20%;
  /* 非必须 */
  position: relative;
  margin-bottom: 2%;
  border-radius: 3px;
  background-color: #a1cbfa;
  border: 1px solid #4290e2;
  box-shadow: 0 2px 2px rgba(0,90,250,0.05),
    0 4px 4px rgba(0,90,250,0.05),
    0 8px 8px rgba(0,90,250,0.05),
    0 16px 16px rgba(0,90,250,0.05);
  color: #fff;
  padding: 15px;
  box-sizing: border-box;
}

 /* 仅用于打印数字 */
div.item::before {
  counter-increment: items;
  content: counter(items);
}

/* 将内容块重排为4列 */
.item:nth-of-type(4n+1) { order: 1; }
.item:nth-of-type(4n+2) { order: 2; }
.item:nth-of-type(4n+3) { order: 3; }
.item:nth-of-type(4n)   { order: 4; }

/* 强制换列 */
.break {
  flex-basis: 100%;
   0;
  border: 1px solid #ddd;
  margin: 0;
  content: "";
  padding: 0;
}
